不同处理对太子参产量及活性成分的影响

通过对不同采收期、不同加工方式及连作方式对太子参产量及活性成分的影响研究表明:产量与多糖含量随着采收期的推迟而下降,采收中期的水分含量最小灰分含量最高;不同加工方式的灰分、多糖、皂苷含量差异显著,阴干的多糖含量最高,其次为烫参,阴干的皂苷含量最高,烫参最低,若考虑活性成分高低则建议采用阴干的加工方式,若考虑实际生产和经济效益则建议采用晒干的加工方式;太子参连作会对太子参的成分有影响,在对比中多糖含量呈显著差异,TR组为CK的1.20倍。

Effect of Harvest,Processing and Cropping on Productivity and Active Ingredient Content of Pseudostellaria heterophylla

By varying the harvest time,processing method and cropping practice,the productivity and content of active ingredients in thePseudostellaria heterophyllaroots harvested were studied.It was found that (a) delayed harvestingreduced the yield and polysaccharide content in the roots;(b) crop harvested at a time between early and late peroid had a lower moisture and higher ash content than either period;(c) processing method affected significantly on the contents of ash,polysaccharides,and saponins of the finished product;(d) the greatest polysaccharide content in thefinished product was achieved bydrying in the shade (F1) followed by blanching (F3);(e) the highestsaponin content was foundin the product dried in the shade,and thelowest by blanching;(f) content ofactive ingredients could be maximized by drying in the shade,but,the processing cost wasminimal if sun-drying was used;(g) continuously cropped P.heterophyllaproduced roots with 1.20 times higherpolysaccharide content than control.
